Use of cyclodextrins for manipulating cellular cholesterol content
Open accessAbstract
Previous studies from this laboratory have demonstrated that exposure of tissue culture cells to cyclodextrins results in rapid cholesterol depletion. In the present study, we have developed experimental systems for using solutions of cyclodextrins, either 2-hydroxypropyl beta-cyclodextrin or methylated beta-cyclodextrin, complexed with varying amounts of free cholesterol to manipulate cell cholesterol content. Cholesterol delivered via the cyclodextrin has been found to be metabolically active, as measured by the acyl-coenzyme A:cholesterol acyltransferase (ACAT)-mediated esterification of [3H]cholesterol in Fu5AH rat hepatoma cells and Chinese hamster ovary cells. The methylated beta-cyclodextrin was found to be a more efficient donor in all cell types studied, with an average cholesterol uptake of at least 100 microg cholesterol/mg protein within 6 h. By modifying the cyclodextrin:cholesterol molar ratio, it is possible to manipulate the cellular cholesterol content of cells, producing conditions ranging from net cholesterol enrichment to depletion. The use of cyclodextrins provides a convenient, precise and reproducible method for modulating the cholesterol content of tissue culture cells.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
